Abstract (en)
An air freshener dispenser (10) includes a two-part housing(15) including a base (20) and a separable cover (40). The base carries a control circuit (80) and the cover carries a dispensing blower (50) and a replaceable cartridge (65) including the freshening agent (66) to be dispensed and a battery (67) for powering the blower. When the cover is removed from the base, the blower is connected directly across the battery for test purposes, but when it is mounted on the base, contact structure (70) on the cover and the base cooperate so that the blower is connected to the battery through the control circuit and is controlled thereby. The control circuit turns off the blower and triggers visible and audible alarm signals after a predetermined time period and/or when the battery voltage gets too low. A photocell (99) turns off the blower and disables the audible alarm in the dark. <IMAGE>
